ABSTRACT:
A bucket dredger has a bucket chain guided over a rocker, the buckets being pivotally interconnected by links of a length shorter than the length of the frame member of the buckets. Each link has an elongated opening with rounded ends in which the pivot pins of the chain are received, the pins associated with each link being pressed apart by rotation of a threaded spindle relative to a threaded socket. The bucket frames have lubricating channels surrounding the pins and sealed against the links.
